GMD Smart Rotate is an app that makes use of the front facing camerato determine your facial orientation, and as such may turn the device’s screen from one mode to another by analyzing the image.The app is loaded with extra features such as the ability to rotate either clockwise or counter clockwise, lock a certain position, force apps to rotate (even if they don’t want to), and more.

This is a feature that can be found on some of the later Samsung devices such as the SGS3 and JB TouchWiz ROMs on SGS2variants as well. However, GMD can be used on any device, as long as it has a front facing camera.

Functionality will obviously be hindered in low light situations, where the camera may not be able to properly identify your face, so be aware of this if you use it.
